Abstract
Description
- The present invention relates to scent releasing devices and more specifically, to a multilayer breathing film-based aroma capsule and an aroma-diffusing heating device using the replaceable multilayer breathing film-based aroma capsule.
- In application of the aroma-diffusing heating device designs of
US Pat. No. 8,668,885 ,US Pat. No. 9,550,358 US Pat. No. 9,498,553 EP Pat. No. 2679249 that are invented by the present inventor, when the heat-transfer container is heated, the heat energy is transferred to the breathing film. Since the breathing film is a plastic film having porous therein, it can be deformed after a long use, causing wrinkles or even affecting the flowing efficiency of the generated aromatic vapor molecules therethrough toward the outside open air. Further, it is not easy to bond the plastic breathing film to the heat-transfer container over the top opening. - Further, other conventional aroma-diffusing heating device designs are also not satisfactory in function and have drawbacks. In the use of conventional aroma-diffusing heating device designs, it is inconvenient to refurnish the aromatic substance. The user needs to prepare a specific heat-transfer container for holding the aromatic substance. When in use, the user needs to take the aromatic substance out of the heat-transfer container carefully, and then to put the aromatic substance in the top accommodation open chamber of the aroma-diffusing heating device, avoiding direct contact of the hands with the aromatic substance.
- Further, after the aromatic substance in the accommodation chamber of the heat-transfer container is used up, the user needs to clean the heat-transfer container. If the heat-transfer container is not well cleaned after each use, a new supply of aromatic substance will be mixed with the residual aromatic substance in the accommodation chamber, giving off a bad smell. Further, if the heat-transfer container is made of a fragile material (for example, ceramics or glass), it may be forced down or broken easily during cleaning, causing the aromatic substance to fall to the ground or to the fluid aromatic substance to contaminate the aroma-diffusing heating device or the surroundings.
- Therefore, it is desirable to provide an aroma-diffusing design that eliminates the drawbacks of the aforesaid prior art designs.
- The present invention has been accomplished under the circumstances in view. It is therefore an object of the present invention to provide a multilayer breathing film-based aroma capsule and an aroma-diffusing heating device using the multilayer breathing film-based aroma capsule that eliminate the drawbacks of the conventional aroma-diffusing heating device designs.
- The invention has the advantages as follows:
- In the operation of the aroma-diffusing heating device to heat the aroma capsule, the breathing film is constantly kept in shape without wrinkles, allowing generated aromatic vapor molecules to smoothly flow through the multilayer breathing film to the outside open air.
- The multilayer breathing film effectively prohibits the fluid aromatic substance from flowing out of the top opening of the aroma capsule to contaminate the aroma-diffusing heating device or the surroundings if the aroma capsule or the aroma-diffusing heating device falls down accidentally during the heating operation.
- After the aromatic substance of the aroma capsule is used up, the aroma capsule can be recycles, and a new aroma capsule can be placed in the aroma-diffusing heating device conveniently, facilitating the application.
- The aroma-diffusing heating device comprises a heating base defining a top accommodation open chamber, an aroma capsule placed in the top accommodation open chamber of the heating base, and a cover member fastened to the heating base to hold the aroma capsule in the heating base.
- In one embodiment of the present invention, the aroma capsule comprises a heat-transfer container defining a top opening, an aromatic substance placed in the heat-transfer container, and a breathing film having a breathable function and bonded to the heat-transfer container over the top opening to hold the aromatic substance in the heat-transfer container. When in use, the aroma capsule is placed in the top accommodation open chamber of the heating base, allowing the aromatic substance to be heated to release aromatic vapor molecules,
- In one embodiment of the present invention, the breathing film comprises a fiber fixation layer defining therein a plurality of first pores, and a microporous layer defining therein a plurality of second pores. The fiber fixation layer is bonded with the microporous layer to create the breathing film that has a breathable function. The microporous layer can be made out of thermoplastic elastomer (TPE). The thermoplastic elastomer (TPE) microporous layer has the second pores therein. The fiber fixation layer is bonded with the thermoplastic elastomer (TPE) microporous layer to create the breathing film. The fiber fixation layer has the characteristics of anti-deformation, good weather resistance and high dimensional stability, and can effectively keep the microporous layer in shape without wrinkles during the heating process, maintaining the breathing function.
- The base fiber material of the fiber fixation layer can be organic or inorganic fibers, such as polymeric fibers, chemical fibers, polyester, cellulose, rayon, glass fibers, and carbon fibers. Alternatively, natural fibers such as plant fibers, wood fibers, silk, and paper fibers can be selectively used. The base fiber material is a porous thin film, fabric or nonwoven fabric in a predetermined shape and size, having a certain degree of heat resistance.
- During the fabrication of the fiber fixation layer, the aperture of the first pores of the fiber fixation layer can be controlled by means of the control of the fiber tightness of the matrix material. Pore forming agent can also be used in the fabrication of the fiber fixation layer to form the desired first pores.
- The microporous layer has a waterproof and moisture permeable function. The microporous layer is a multi-(micro) hole matrix material, or a microporous film or fabric made of a matrix material (such as polymer) with the application of a hole forming agent (gas or filler). The microporous layer defines therein a plurality of second pores. During the fabrication of the microporous layer, multiple micro pores are formed therein subject to the use of a hole forming agent. McCormark
WO 96/19346 - In some embodiments of the present invention, the microporous layer is selected from, but not limited to, films made using, for example, thermoplastic elastomer (TPE) compositions, which are prepared by melt-plasticizing the film, or by, for example, stretching the film to create micro pores. Filler particles or hole forming agent can be selectively used for making the microporous layer to create the desires micro holes. The applied filler material, oil or hole forming agent is mixed with the thermoplastic elastomer (TPE). Forming, solution film forming, stretching, electrostatic spinning and direct drilling techniques can be selectively used for making a thin film with µm grade micro pores of size even below 10µm. Precision instrument or etching technique can be employed for the creation of the desired micro pores. The use of a thermoplastic elastomer (TPE) film without pores can simply selectively allow gas to pass. The open space of each of the second pores allows the released aromatic vapor molecules to pass therethrough. The choice of microporous layer with moisture permeability and good masking properties can block melted aromatic substance or spices fluid, prohibiting melted aroma wax or essential oil from passing therethrough. The second pores of the microporous layer provide waterproof and moisture permeable effects. The microporous layer and the fiber fixation layer are bonded together to create the desired breathing film that is then bonded to the heat-transfer container over the top opening to block the melted aromatic substance from falling to the outside of the aroma capsule.
- In one embodiment of the present invention, the thermoplastic elastomer (TPE) microporous layer defines therein a plurality of second pores. Preferably, the thermoplastic elastomer (TPE) is thermoplastic urethane (TPU); the fiber fixation layer is TETORON or polyethylene terephthalate (PET). TETORON is formed by the condensation of terephthalic acid and ethylene glycol linear polymer. The fabric made out of polyethylene terephthalate is called as Dacron that is hot pressed to create the fiber fixation layer. Glass fiber can be added to polyethylene terephthalate to enhance stiffness and heat resistance with the first pores defined therein. Polyester products such as polyester fabric or nonwoven fabric can be used as a substitute. Silk cloth can also be selectively used for the fiber fixation layer.
- In one embodiment of the present invention, the heat-transfer container is selected from the material group consisting of polymers, metal, ceramic and wood. The polymers can be plastic, polyester plastic, PCTG, TPU, PET or PP.
- In one embodiment of the present invention, the heat-transfer container further comprises a rim extended around the top opening thereof; the breathing film is bonded to the rim of the heat-transfer container.
- In one embodiment of the present invention, the thermoplastic elastomer (TPE) microporous layer of the breathing film is bonded to the heat-transfer container over the top opening.
- In one embodiment of the present invention, the heat-transfer container is made out of polymers, for example, the heat-transfer container is made out of poly chloro terephthalate glycol (PCTG). The thermoplastic elastomer microporous layer is made out of thermoplastic urethane (TPU) to create the breathing film. The TPU material of the breathing film is bonded to the PCTG heat-transfer container over the top opening and the aromatic substance. The use of TETORON or PET fiber fixation layer can be constantly maintained in shape and kept free of the effect of weather. The first pores of the fiber fixation layer are relatively larger than the second pores of the TPU microporous layer. During the operation of the aroma-diffusing heating device to heat the aroma capsule, the TETORON or PET fiber fixation layer does not shrink or expand during the heating process, and effectively keeps the TPU microporous layer in shape without collapsing the second pores, and thus, the breathing film can be maintained in a good looking, and the ventilation of the second pores of the TPU microporous layer is maintained in function. The TPU microporous layer works like the functioning of a GOTEX fabric that prohibits external water molecules from passing through the second pores of the TPU microporous layer into the inside of the aroma capsule to wet the aromatic substance. During the operation of the aroma-diffusing heating device to heat the aromatic substance, a high concentration of aromatic vapor molecules is generated. The aromatic vapor molecules then flow through the second pores of the TPU microporous layer of the breathing film and then the first pores of the TETORON or PET microporous layer to the outside open air.
- In one embodiment of the present invention, the size of the first pores of the breathable aperture is greater than or equal to the size of the second pores of the breathable aperture, i.e., the ventilatory capacity per unit area of the first pores of the fiber fixation layer is greater than or equal to the ventilatory capacity per unit area of the second pores of the microporous layer.
- In one embodiment of the present invention, the porosity of the first pores and the porosity of the second pores are different.
- In one embodiment of the present invention, the PET fiber fixation layer and the TPU microporous layer are bonded together using hot-press fusion or high-frequency sealing technology to create the breathing film. The TPU material of the breathing film is bonded to the rim of the PCTG heat-transfer container over the top opening.
- In one embodiment of the present invention, the heat-transfer container further comprises a sealing cover bonded to the top opening over the breathing film and the aromatic substance to seal the aromatic substance in the heat-transfer container, preventing the aromatic substance from being in contact with the atmosphere.
- In one embodiment of the present invention, the aroma-diffusing heating device further comprises a cover member fastened to the heating base to hold the aroma capsule in the heating base. The cover member defines therein a hole for the passing of the generated aromatic vapor molecules to the outside open air.
- In one embodiment of the present invention, the aromatic substance is selected from the group consisting of aromatic wax, perfume, balsam, sesame oil mixture and essential oil.
- The invention achieves the effects as follows:
- In the operation of the aroma-diffusing heating device to heat the aroma capsule, the breathing film is maintained in shape, allowing the aromatic vapor molecules released by the aromatic substance to flow smoothly through the breathing film to the outside open air
- After the aromatic substance of the aroma capsule is used up, the aroma capsule can be recycled, and another new aroma capsule can be conveniently put in the aroma-diffusing heating device for application.

FIGS. 1-6 , an aroma-diffusingheating device 1 in accordance with the present invention is shown. The aroma-diffusingheating device 1 comprises aheating base 10 defining a top accommodationopen chamber 100, and anaroma capsule 12 detachably accommodated in the top accommodationopen chamber 100 of theheating base 10 and heatable by theheating base 10 to give off fragrance. Thearoma capsule 12 comprises a heat-transfer container 120 defining atop opening 1200, anaromatic substance 122 held in the heat-transfer container 120, and a breathing film bonded to the heat-transfer container 120 over thetop opening 1200 and thearomatic substance 122 to allow moisture vapor to be transmitted through the material. - Referring to
FIGS. 1-6 , in one embodiment of the present invention, thebreathing film 126 comprises afiber fixation layer 1261 and amicroporous layer 1262 of excellent moisture permeability. Thefiber fixation layer 1261 defines therein multiplefirst pores 1263. Themicroporous layer 1262 defines therein multiplesecond pores 1264. Thefiber fixation layer 1261 and themicroporous layer 1262 are bonded together to form thebreathing film 126 with the breathable and waterproof function. Themicroporous layer 1262 is preferably made out of thermoplastic elastomer (TPE) compound. Thefiber fixation layer 1261 is preferably made out of polyester. The polyesterfiber fixation layer 1261 and the thermoplastic elastomer (TPE)microporous layer 1262 are bonded together to form thebreathing film 126 that is breathable. The breathable aperture of thefirst pores 1263 is greater than the breathable aperture of thesecond pores 1264, facilitating outward transmittance of air. Thebreathing film 126 is bonded to the heat-transfer container 120 over thetop opening 1200. Through thesecond pores 1264 of the thermoplastic elastomer (TPE)microporous layer 1262, thearoma capsule 12 provides waterproof and moisture transmissive functions, keeping thearomatic substance 122 fresh. - The thermoplastic elastomer (TPE)
microporous layer 1262 and thefiber fixation layer 1261 can be bonded together using hot-press fusion or high-frequency sealing technology. Since thefirst pores 1263 of thefiber fixation layer 1261 are relatively lager than thesecond pores 1264 of the thermoplastic elastomer (TPE)microporous layer 1262, the heated aromatic substance vapor molecules can go throughsecond pores 1264 of the thermoplastic elastomer (TPE)microporous layer 1262 toward thefirst pores 1263 of thefiber fixation layer 1261. - In application, the
aroma capsule 12 is heated in the aroma-diffusingheating device 1 to release a pleasant smell at a temperature below 90°C. During the heating process, thefiber fixation layer 1261 does not shrink or expand the size and can keep the thermoplastic elastomer (TPE)microporous layer 1262 in shape, and thus, the surface of thebreathing film 126 can be constantly maintained smooth without wrinkles. During the heating process,aromatic substance 122 keeps releasing aromatic vapor molecules that flow smoothly through thesecond pores 1264 of the thermoplastic elastomer (TPE)microporous layer 1262 and thefirst pores 1263 of thefiber fixation layer 1261 toward the atmosphere outside thearoma capsule 12, however, the liquid phase aromatic substance is prohibited from passing through thesecond pores 1264, ensuring safety application of thearoma capsule 12. - Further, the
aromatic substance 122 is selected from the group consisting of aromatic wax, perfume, balsam, sesame oil mixture and essential oil. In the case an aromatic wax is used for thearomatic substance 122 of thearoma capsule 12, theheating base 10 simply needs to heat the aromatic wax to the melting point of the aromatic wax, causing the aromatic wax to release aromatic vapor molecules through thebreathing film 126 toward the outside open air. In the case a sesame oil mixture or essential oil is used for thearomatic substance 122 of thearoma capsule 12, the sesame oil mixture or essential oil is heated to release aromatic vapor molecules through thebreathing film 126 toward the outside open air. When compared to related existing commercial products, thebreathing film 126 of the present invention will not deform during the heating process, and the released aromatic vapor molecules can flow through thebreathing film 126 toward the outside open air efficiently. - Further, the heat-
transfer container 120 is made out of polymers. In one embodiment, the heat-transfer container 120 is made out of plastics selected from the group consisting of polyester plastic, poly chloro terephthalate glycol (PCTG), polyethylene terephthalate (PET), propylthiouracil (PTU) and polypropylene (PP). The plastic heat-transfer container 120 does not melt or deform at the above-mentioned heating temperature, and can efficiently transfer heat energy from theheating base 10 to thearomatic substance 122. In one embodiment of the present invention, the heat-transfer container 120 is made out of PCTG, capable of transferring heat energy from theheating base 10 to thearomatic substance 122 for causing thearomatic substance 122 to release a pleasant smell. Further, the heat-transfer container 120 has excellent ductility and toughness and is not easy to rapture. It will not be damaged when heating by the aroma-diffusing heating device, and can efficiently transfer heat energy from the aroma-diffusing heating device to the aromatic substance. When compared to fragile pottery and glass heat-transfer containers of conventional aroma-diffusing heating devices, the heat-transfer container 120 has the advantage that thetop opening 1200 of the heat-transfer container 120 can easily be bonded with thebreathing film 126, i.e., thethermoplastic microporous layer 1262 of thebreathing film 126 can be bonded to thetop opening 1200 of the heat-transfer container 120 by heat or with an adhesive. The bonding effect is better than the prior art design. After bonding, thebreathing film 126 will not fall off. - Referring to
FIGS. 4 ,5 and6 , in application, the user simply needs to put thearoma capsule 12 in the top accommodationopen chamber 100, and then to electrically conduct theheating base 10, melting the aromatic substance 122 (such as aromatic wax or essential oil) to emit aromatic vapor molecules. In the heating process, the emitted aromatic vapor molecules go from thearoma capsule 12 through thesecond pores 1264 of themicroporous layer 1262 of thebreathing film 1261 and then thefirst pores 1263 of thefiber fixation layer 1261 to the surrounding air while thebreathing film 1261 stays in shape and keeps breathing. - After the
aromatic substance 122 is used up, the heat-transfer container 120 can be thrown away or recycled, and anew aroma capsule 12 can be put in the top accommodationopen chamber 100 of the aroma-diffusingheating device 1. Thus, the user's hand will not be contaminated by thearomatic substance 122. Further, the user does not necessary to clean the top accommodationopen chamber 100 of the aroma-diffusingheating device 1. Even if the aroma-diffusingheating device 1 falls down accidentally during application, the meltedaromatic substance 122 of thearoma capsule 12 is still held in the heat-transfer container 120 by thebreathing film 126 and will not flow to the outside of the aroma-diffusingheating device 1 to cause contamination or dangers. - Further, balsam, spices, sesame oil mixture can be selectively used for the
aromatic substance 122 to substitute for aromatic wax. The application of these substances is same as the use of aromatic wax. - Referring to
FIGS. 1 ,2 ,3 and4 , in one embodiment of the present invention, thearoma capsule 12 further comprises arim 1202 extended around thetop opening 1200, and thebreathing film 126 is bonded to therim 1202. Preferably, the thermoplastic elastomer (TPE)microporous layer 1262 is peripherally bonded to therim 1202 of the heat-transfer container 120 over thetop opening 1200 to secure thebreathing film 126 to the heat-transfer container 120. - Referring to
